garded. Their names are formed by the combination of the Greek 
numeral expressing the required number, with the termination andria, 
which has reference to the supposed male office of the stamens in the 
process of fertilization. 
CHARACTERS OF THE LINNZAN CLASSES. 
12. These classes, therefore, stand simply as shown in the figures repre-

is here particularly made.

for in the next Class, Potyanprta, the number of stamens is also twenty 
or more. They are distinguished by the mode of insertion of the sta- 
mens, these appearing to arise from the calyx in the former, and from 
the disk or receptacle in the latter. This distinction which will here- 
after be shown-to be i important in the Natural system, will be at once
